Britney -- Ashamed of Her Own Face?!

Brit stopped for a fill-up yesterday -- no, not for Provigil and collagen -- gas. And Brit did a bizarre thing -- she hid her face from paparazzi! Unbeweaveable!

Spears went deep undercover at a 76 gas station last night, as paps begged for Britney to remove the sweater covering her daily-snapped mug. Brit wouldn't budge though, and even tried to drive off with her face still covered. All feet remained intact.

One thing's for sure -- her new car is as big a gas guzzler as the last one!
